Patent GB-1033403-A (GB)
Title: Improvements in or relating to capacitors and to methods of manufacture thereof
IPC: H01G4/228
Filed: 1963-03-20
Abstract: A method of forming a two-electrode capacitor comprises oxidizing a surface film of a first electrode of Ta, Nb, Ti, Bi or Al forming a layer of insulating material on the oxidized surface to fill fissures or cracks formed therein during the oxidation process, and depositing a second electrode on the surface.  The first electrode may be deposited on glass or ceramic.  In one example a layer 12 of tantalum 4000 Angstroms thick is deposited on a glass plate 10 by cathode sputtering and anodized, except for an end contact 16, in an electrolyte comprising a 1% aqueous solution of ammonium borate.  The voltage across the growing oxide layer is raised to and maintained at 100 volts for at least 20 minutes to form an oxide layer 1600 Angstroms thick.  The layer is coated with aluminium by evaporation in a vacuum chamber so that aluminium fills any cracks in the layer, and the surface aluminium is removed by etching in aqueous potassium hydroxide. The surface is then anodized in a 1% aqueous solution of boric acid with the maximum forming voltage at 125 volts.  Counter electrodes 18 and 20 are then deposited by evaporation or cathode sputtering. These electrodes may be of aluminium or tantalum. In another example the anodized tantalum surface is placed in an evaporation chamber to 10-4 to 10-5 mm. and aluminium is evaporated slowly on to the surface, e.g. over a period of about 2 minutes instead of the normal 15 seconds. The residual oxygen and water vapour causes partial oxidation of the aluminium as it condenses on the metal oxide layer, and the deposited layer of aluminium serves as a counter electrode.

Title: Improvements in battery equipment for miners' electric lamps
Inventor: LLOYD HARRY
IPC: F21V23/00
Filed: 1950-05-04
Abstract: 681,303. Batteries. MINISTER OF FUEL & POWER. May 2, 1951 [May 4, 1950], No. 11084/50. Class 53. [Also in Group XXXV] The cover 1 of an accumulator intended for use with a miner's head-lamp encloses a rectifier 3 which is connected to one pole 8 of the accumulator and to a coil 4 connected to the other pole.

Filed: 1952-05-02
Abstract: Non-staling bakery products are made by incorporating into the dough, in addition to the usual ferments, a preparation of a -amylase derived from bacteria, e.g. Bacillus mesentericus or Bacillus subtilis, which preparation is active at temperatures above the starch gelatinization temperature and is employed in amount insufficient for the production of a soggy crumb, and thereafter baking the dough.
Patent GB-937550-A (GB)
Title: Process for the separation of azeotropic mixtures containing alcohols or phenols
IPC: C07C7/148
Filed: 1961-03-27
Abstract: Azeotropic mixtures containing an alcohol or phenol and a non-hydroxylated organic compound are separated by converting the alcohol or phenol into an acetal by reaction with an aldehyde in the presence of a catalyst, azeotropically distilling off the water formed and then separating the non-hydroxylated component of the mixture from the acetal by distillation, which may be fractional distillation.  The original mixture may contain an excess of one or the other of the components over the quantity required to form an azeotropic mixture.  The preferred aldehyde for use in the acetal-forming reaction is formaldehyde, preferably used as paraformaldehyde.  Specified catalysts for promoting the formation of the acetal are sulphuric or hydrochloric acid, calcium chloride, p-toluene sulphonic acid, cation exchangers, aluminium chloride, zinc chloride, pyridine hydrochloride, sodium bisulphate, iron chloride, orthosilicic acid ester, titanic acid esters and dimethyl sulphite. The process may be effected continuously in a fractionation column under normal, reduced or raised pressure.  Examples are given in which the following mixtures are separated after acetalisation of the alcoholic or phenolic component with formaldehyde:-(1) n-propyl acetate and n-propanol; (2) n-propyl acetate and allyl alcohol; (3) n-butyl acrylate and n-butanol; (4) n-hexyl acrylate and n-hexanol; (5) 2-ethylhexyl acrylate and 2-ethylbutanol; (6) 2-ethylhexyl acrylate and 2-ethylhexanol; (7) n-butyl methacrylate and n-butanol; (8) phenyl acetate and o-chlorophenol; (9) benzyl formate and benzyl alcohol; (10) diethyl carbonate and n-butanol; (11) chlorobenzene and n-butanol; (12) toluene and n-butanol; (13) carbon tetrachloride, dioxane and n-propanol; (14) n-butyl bromide and n-propanol; (15) diethyl ketone and n-propanol; (16) cyclohexane and n-propanol; and (17) n-propyl ether and n-propanol.  An example is given also in which a mixture of glycol diacetate and glycol is acetalised with diethylacetaldehyde.

Title: Improvements in feed mechanism for the slides of metal cutting or other machine tools
IPC: B23Q1/28
Filed: 1935-04-11
Abstract: 440,864. Feeding and clamping mechanism for machine slides. SCHOENING, H., 23, Franziskanerweg, Frohanau, Berlin. April 11, 1935, No. 11262. Convention date, Nov. 24, 1934. [Class 83 (iii)] In a feeding and clamping device for a machine-tool slide, a feed motor actuates a reciprocating member to effect first the unclamping and then the feed movement of the slide. In Fig. 1 the motor (not shown), drives a spindle a which carries a rotatable but axially fixed nut b and a slidable but non-rotary nut c. When the screw a rotates the nut c first moves axially and in so doing operates lever mechanism d, e and clamping levers h, Fig. 2, to unclamp the sleeve member l from the column m of a radial drilling machine. After the unclamping has been effected, one of the projections s, q engages a projection r on the nut b and prevents it from turning. The nut b then acts as a feed nut and the desired feed movement of the slide occurs. At the end of the feed movement the spindle a is reversed, thus causing the nut c to move axially to reclamp the slide l (Fig. 1 position) at which point the motor is stopped. In a modification, Fig. 4, movement of the slide l<1> is effected by a fixed rack w and pinion v. A pinion p<1> drives a nut c<1> which then moves axially along a screw o to actuate the lever system r<1>, s<1>, ql to cause unclamping of the slide. The nut then engages one of the abutments t, u after which the screw o rotates with the nut and actuates worm-gearing n, x, and the rack-and-pinion gearing to impart the desired slide feed movement. The reversal of the motor returns the nut c<1> to clamp the slide and the motor is finally stopped by the opening of a switch by the clamping mechanism. A cam working between flanges or a sleeve may be used instead of the nut c<1>.

Apparatus for applying cue markings to kinematograph films comprises a bed 12 on which the film strip may be placed and a cover 14 adapted to be positioned on the bed over the film strip, the cover 14 having apertures 36 therein, each in register with a picture frame on the film strip positioned on the bed so that a tool may be inserted in the apertures to mark the film strip, the apertures being so arranged that all the marks on the film will be similarly placed on each picture frame and thus ensure the presentation of a clear cue mark during the projection of the film strip. The flat surface 18 of the bed has two upstanding pins 20 so positioned that film sprocket holes can be fitted over them to hold the film, emulsion side upward, and with the sound track spaced away from the pins, over the bed with one or both end edge 22 of the bed in alignment with a mask line between adjacent frames. A hinge-pin 28 journalled in lugs 26 passes through a part of the cover 14 which swings down so that its flat underside 32 clamps the film on the bed, being held in place by a spring catch 48. Holes 34 engage the pins 20. Four apertures 36 are formed in the cover 14 by means of bushes of hardened steel, and occupy similar positions with respect to the frames of the film strip. The tool has a tube with teeth at one end, which tube fits the apertures 36 closely, and is inserted in each aperture in turn and rotated to scrape a circular mark on the emulsion of each frame. The length of the tube is preferably such that the toothed end penetrates the emulsion layer but is prevented from going further by the handle, which is wider than the apertures and may be knurled. The size of the apparatus and the arrangement of the pins and apertures may be varied for use with different sizes of film.
